Australian Milking Zebu

In an effort to overcome the problems of traditional dairy breeds performing at reduced levels under hot, humid and tick-infested conditions, the Commonwealth Scientific & Industrial Research Organization (CSIRO) developed the Australian Milking Zebu (AMZ). This began in the mid-1950’s with the introduction of Pakistani Sahiwal and Red Sindhi dairy cattle, which were mated initially to high-producing Jersey cattle. Later, some infusion of Illawarra, Guernsey and Holstein-Friesian bloodlines occurred.

Careful interbreeding of the half-bred progeny, combined with strict selection criteria, have resulted in the AMZ breed. Selection is for heat tolerance, tick resistance and milk production alone.

Mature purebred AMZ cows produce an average of 2,700 liters of milk over a 12 month period, while AMZ cross Friesian cows average more than this. Quality of milk is very high and protein level is approximately 3.5 to 4 percent.
